The main problem of the world is population and unemployment. The economic crisis has devoured us.Young people need work. For example, if it's a child from a dysfunctional family that can not get away with it. I believe that a child can get a job on a part-time basis. After school or on weekends, on vacation days or just in his spare time, he can go to work. First, it will make it more independent. Teach you how to manage money correctly.Secondly, it will help his family financially. I think this reasons give the answer for my opinion about part-time work.
Как-то так, я старалась)
